COLLAR.

SPECIFICATION forming part of Letters Patent No. 641,691, dated January23, 1900. Application filed April18, 1898. Serial No. 678,095.(Nomodeli) To a whom it may concern:

Be it known that I, HENRY LAWRENCE GUL- LINE, of Granby, in the countyof Shefford and Province of Quebec, Canada, have invented certain newand useful Improvements in Horse-Collars; and I do hereby declare thatthe following is a'full, clear, and exact description of the same.

This invention relates more particularly to the rims of horse-collars,and has for its object to produce a metal rim of simplified and improvedconstruction.

The invention consists of a horse-collar rim of tubular form with aclosed flange extending the full length thereof, said rim and flangeconsisting of a single strip of metal curved into tubular form andhaving one of its side edges extending in a continuous straight linefrom the curve, the other side edge offset and doubled over saidstraight edge.

For full comprehension, however, of the invention reference must be hadto the accompanying drawings, forming a part of this specification, inwhich like symbols indicate corresponding parts, and wherein- Figure 1is a rear view of a metal rim constructed according to my invention;Fig. 2,

a side view of the same; Figs. 3, 4, and 5, cross-sectional views of thesame,respectively, on lines 3 3, 4 4, and 5 5, Fig. 1; and Fig. 6, across-sectional view of a complete collar provided with the improvedrim.

The metal rim is formed of a single piece of metal a of such resiliencyas will allow it when bent into the tubular body form shown and providedwith the tangential flange 1), extending throughout its entire length,to be bent into rim form and opened and closed at the peak at will, thusdispensing with any form of hinge or catch at the throat portion andmaking the rim in one piece instead of two separate sections. The rim incross-sec tion has one of its side edges extending in a continuousstraight line from the curve and the other side edge offset and doubledover said straight edge, so that in bending the tubular length intotherim form there will be no chance of the tube opening along its length.

It will be at once apparent that by my improvement a vast saving in thecost of manufacturing these metal rims is effected besides the impartingof great additional strength thereto and the doing away with anypossibility of breakingat the throat portion through insecure orimperfect riveting, which might occasionally arise in the constructionof horsecollar rims made in two halves and joined together at the throatby a hinge or other at tachment.

In order to manufacture my improved rim, I first cut the sheet metalinto strips of a sufflcient width to enable them to be folded in afolding-machine to produce a straight tube ing bent and to allow of thetube being bent while cold. The tube is then bent midway of its lengthover a mandrel of a diameter equal to that required for the throatportion of the rim, and the ends are then and preferably in the sameoperation bent toward one another over a second mandrel of such form aswill produce the desired shape at the peak, the .closing of the flangeserving, as before mentioned, to prevent any possibility of thetubeopening along its length.

What I claim is as follows:

As a new article of manufacture, a horsecollar rim of tubular form witha closed flange extending the full length thereof, said rim and flangeconsisting of a single strip of metal curved into tubular form andhaving one of its side edges extending in a continuous straight linefrom the curve, the other side edge offset and doubled over saidstraight edge, as set forth.

In testimony whereof I have affixed my sig nature in presence of twowitnesses.

HENRY LAWRENCE GULLINE.
